asp.net-mvc - 单元测试 Url.Action

Question

我正在尝试对从 DotNetOpenAuth 示例中获得的代码进行单元测试，但我很难让 UrlHelper 在我的测试中工作。

在我的 Controller 上的 LogOn ActionResult 的某处，它调用了以下 UrlHelper。以下示例是该 ActionResult 的简化版本。

public ActionResult TestUrlHelper()
{
    var test = Url.ActionFull("LogOnReturnTo");
    return View();
}

我的测试看起来像这样:

[Test]
public void TestTest()
{
    AccountController controller = GetAccountController();
    var result = controller.TestUrlHelper();
}

这是 UrlHelper 的扩展方法:

internal static Uri ActionFull(this UrlHelper urlHelper, string actionName)
{
    return new Uri(urlHelper.RequestContext.HttpContext.Request.Url, 
                   urlHelper.Action(actionName));

}

我从下面的question得到的GetAccountController方法.我尝试根据自己的需要稍微调整设置，但我不得不承认我并不完全理解。

private static AccountController GetAccountController()
{
    var MockIFormsAuthentication = new Mock<IFormsAuthentication>();
    var MockIOpenIdRelyingParty = new Mock<IOpenIdRelyingParty>();
    var MockRealm = new Realm("http://www.google.be");

    var routes = new RouteCollection();
    MvcApplication.RegisterRoutes(routes);

    var request = new Mock<HttpRequestBase>(MockBehavior.Strict);
    request.SetupGet(x => x.ApplicationPath).Returns("/");
    request.SetupGet(x => x.Url).Returns(new Uri("http://localhost/Account/LogOnReturnTo", UriKind.Absolute));
    request.SetupGet(x => x.ServerVariables).Returns(new System.Collections.Specialized.NameValueCollection());

    var response = new Mock<HttpResponseBase>(MockBehavior.Strict);
    response.Setup(x => x.ApplyAppPathModifier("/Account/LogOnReturnTo")).Returns("http://localhost/Account/LogOnReturnTo");

    var context = new Mock<HttpContextBase>(MockBehavior.Strict);
    context.SetupGet(x => x.Request).Returns(request.Object);
    context.SetupGet(x => x.Response).Returns(response.Object);

    var Controller = new AccountController(MockIFormsAuthentication.Object, MockIOpenIdRelyingParty.Object, MockRealm);
    Controller.ControllerContext = new ControllerContext(context.Object, new RouteData(), Controller);
    Controller.Url = new UrlHelper(new RequestContext(context.Object, new RouteData()), routes);

    return Controller;
}

我得到的错误是:

HttpResponseBase.ApplyAppPathModifier("/Home/LogOnReturnTo") invocation failed with mock behavior Strict.

非常感谢任何朝着正确方向的帮助或插入

MockBehavior.Strict 将

Make mock behave like a "true Mock", raising exceptions for anything that doesn't have a corresponding expectation.

(来自 Moq wiki)

因此，如果您将 MockBehavior 设置为 Loose，它:

never throws and returns default values or empty arrays, enumerables, etc. if no expectation is set for a member
